Question 1
What is the study of the structure of the human body?
A) Physiology
B) Histology
C) Anatomy
D) Cytology
Correct Answer: C) Anatomy
Rationale: Anatomy is the branch of science that deals with the structure of the
human body. Physiology is the study of function, histology is the study of tissues,
and cytology is the study of cells.

Question 2
Which plane divides the body into left and right portions?
,A) Transverse plane
B) Frontal plane
C) Sagittal plane
D) Coronal plane
Correct Answer: C) Sagittal plane
Rationale: The sagittal plane divides the body into left and right portions. The
transverse plane divides the body into superior and inferior portions, and the
frontal (coronal) plane divides the body into anterior and posterior portions.

Question 3
The heart is located in which body cavity?
A) Abdominal cavity
B) Pelvic cavity
C) Thoracic cavity
D) Cranial cavity
Correct Answer: C) Thoracic cavity
Rationale: The heart is located within the thoracic cavity, specifically in the
mediastinum. The abdominal cavity contains digestive organs, the pelvic cavity
contains reproductive and excretory organs, and the cranial cavity contains the
brain.

Question 4
Which term means toward the front of the body?
A) Posterior
B) Dorsal
C) Anterior
D) Superior
Correct Answer: C) Anterior
Rationale: Anterior (or ventral) means toward the front of the body. Posterior (or
dorsal) means toward the back. Superior means toward the head, and inferior
means toward the feet.

Question 5
The smallest structural and functional unit of life is the:
A) Tissue
B) Organ
C) Cell
D) Molecule
Correct Answer: C) Cell
, Rationale: The cell is the smallest structural and functional unit of life. Tissues are
groups of similar cells, organs are composed of multiple tissues, and molecules are
smaller than cells.
---
Question 6
Which of the following is an example of a negative feedback mechanism?
A) Blood clotting
B) Regulation of body temperature
C) Uterine contractions during childbirth
D) Lactation
Correct Answer: B) Regulation of body temperature
Rationale: Negative feedback mechanisms reverse a deviation from a set point,
maintaining homeostasis. Body temperature regulation is a classic example. Blood
clotting, uterine contractions, and lactation are examples of positive feedback
mechanisms.
